The modern sprite workflow
Managing 2D assets often involves converting between static sheets (for game engines) and playable video formats (for previews or sharing). This tool bridges that gap entirely in your browser.
Sheet to Animation
Upload a PNG strip or grid. Our visual editor allows you to align a red "cut grid" over your sprites. The tool then slices them up and reconstructs them into a looping GIF.
Animation to Sheet
Upload an MP4, WEBM, or GIF. The tool samples frames at your specified rate (FPS) and tiles them automatically into a single transparent PNG image.
Visual Editor & Auto-Detect
When you upload a spritesheet, the tool analyzes the aspect ratio. If it detects a long horizontal strip, it automatically guesses the column count.
You can fine-tune this using the sliders in the settings panel. Look for the Red Grid Overlay on your image—everything inside a red box becomes one frame of animation.
Technical details
- Transparency: Fully supported. The background checkerboard helps you distinguish transparent areas from white pixels.
- Performance: Large sheets (4K+) consume significant RAM. If the browser tab freezes, try resizing your source image first.
- Output: Animations export as GIF (infinite loop). Generated sheets export as PNG (lossless).
